PUTTING IT INTO PRACTICE
Vector Cross Product: a worked example
The values below are an illustrative example, not a recommendation. Replace them with measurements or assumptions that match your question.
| Input | Example value |
|---|---|
| A x | 1 |
| A y | 0 |
| A z | 0 |
| B x | 0 |
| B y | 1 |
| B z | 0 |
| Result | 0, 0, 1 |
- Check the input labels and enter the example values above.
- Apply the relationship: A×B = (AyBz−AzBy, AzBx−AxBz, AxBy−AyBx)..
- The result is 0, 0, 1 , rounded for display.
How to interpret your result
Uses a right-handed coordinate system; reversing the input order reverses the result sign.
Keep coordinate units consistent along every axis. Distance is non-negative, while slope and dot product can have signs. A vertical line has undefined slope because the horizontal coordinate change is zero.
Frequently asked questions
Does a zero dot product always mean the vectors are perpendicular?
Two nonzero vectors with zero dot product are perpendicular. The zero vector needs separate treatment because it has no defined direction.
When is the vector cross product calculator useful?
Find the three components of the cross product of two 3D vectors. Uses a right-handed coordinate system; reversing the input order reverses the result sign.
How do I use the vector cross product calculator?
Enter a x, a y, a z, b x, b y, b z. The result updates automatically. Use the units shown beside each input; the example values illustrate the method.
Which formula does this calculator use?
A×B = (AyBz−AzBy, AzBx−AxBz, AxBy−AyBx)..
What should I check before using the result?
Uses a right-handed coordinate system; reversing the input order reverses the result sign.
How are results rounded?
Scalar numbers display up to six decimal places, with scientific notation for very large or small values. Text, fraction, date and schedule outputs use the format described on the tool. Intermediate calculations use JavaScript floating-point arithmetic. Keep sensible precision for your measurements.
